Abstract: It is capable of authentication by transmitting through light emitted from a flash of a smart mobile according to foregoing solution of the problem, security and stability can be improved in comparison with other authentication systems such as an ID, a password and a public authentication which are necessary to a bank task, a personal authentication, an identity authentication and a transaction remittance. And, even if the smart mobile is lost or a stranger acquiring this are misappropriating, cryptography such as patterns cannot be solved thereby it is not available. Further, carrying is easy to use anywhere regardless of the place because the transaction is available using a flash equipped to the smart mobile.
